I've always reloaded my own rips (but not the Sparky stuff) back into Quartet as it (handily) made sure the files were the correct size in case I'd over-ripped them in the past. Vague memories of having the same problems back in the day.
I vaguely remember doing that with the deathbringer music.(IIRC)
I tried and gave up with the Projectyle ones as the samples were stored reversed or soemthing crazy & I think the file headers had been mucked about with too, That said I think I had done a sector dump file of the disk which didn't help.
I always wanted an ultimate ripper cart but never got round to it! I Used the Adrenalin & Probe ST, and sometimes messed with loading files into STOS.
